Chris Hedges, who graduated from seminary at Harvard Divinity School and worked for many years as a foreign correspondent for The New York Times, warns that the Christian Right is the most dangerous mass movement in American history.

Dr. James Luther Adams, my ethics professor at Harvard Divinity School, told his students that when we were his age—he was then close to 80—we would all be fighting the “Christian fascists.”

The warning, given 25 years ago, came at the moment Pat Robertson and other radio and television evangelists began speaking about a new political religion that would direct its efforts toward taking control of all institutions, including mainstream denominations and the government. Its stated goal was to use the United States to create a global Christian empire. This call for fundamentalists and evangelicals to take political power was a radical and ominous mutation of traditional Christianity. It was hard, at the time, to take such fantastic rhetoric seriously, especially given the buffoonish quality of those who expounded it. But Adams warned us against the blindness caused by intellectual snobbery. The Nazis, he said, were not going to return with swastikas and brown shirts. Their ideological inheritors had found a mask for fascism in the pages of the Bible.

He was not a man to use the word fascist lightly. He had been in Germany in 1935 and 1936 and worked with the underground anti-Nazi church, known as the Confessing Church, led by Dietrich Bonhoeffer. Adams was eventually detained and interrogated by the Gestapo, who suggested he might want to consider returning to the United States. It was a suggestion he followed. He left on a night train with framed portraits of Adolf Hitler placed over the contents of his suitcases to hide the rolls of home-movie film he had taken of the so-called German Christian Church, which was pro-Nazi, and the few individuals who defied the Nazis, including the theologians Karl Barth and Albert Schweitzer. The ruse worked when the border police lifted the tops of the suitcases, saw the portraits of the Führer and closed them up again. I watched hours of the grainy black-and-white films as he narrated in his apartment in Cambridge.

Adams understood that totalitarian movements are built out of deep personal and economic despair. He warned that the flight of manufacturing jobs, the impoverishment of the American working class, the physical obliteration of communities in the vast, soulless exurbs and decaying Rust Belt, were swiftly deforming our society. The current assault on the middle class, which now lives in a world in which anything that can be put on software can be outsourced, would have terrified him. The stories that many in this movement told me over the past two years as I worked on “American Fascists: The Christian Right and the War on America” were stories of this failure—personal, communal and often economic. This despair, Adams said, would empower dangerous dreamers—those who today bombard the airwaves with an idealistic and religious utopianism that promises, through violent apocalyptic purification, to eradicate the old, sinful world that has failed many Americans.
